In 1975, after sporadic work with DC and Marvel, Broderick joined the team at Atlas Comics. His time at Atlas was short-lived, and Broderick soon found himself back at Marvel, working on various titles for their black-and-white line, Curtis Magazines. This led to runs on Captain Marvel and then The Micronauts.[4] He drew the Micronauts series from #19 (July 1980) to #34 (Oct. 1981).[5]

After ten years at DC, Broderick's relationship with that company soured. According to him, he "was being abused by [his] editors, Andy Helfer and Kevin Dooley, and was really just fed up with their attitude."[4] Shooter was no longer at Marvel which offered him work again and Broderick returned, where he worked as the regular penciller first on Alpha Flight[4] and Doom 2099.[13]

In 2003, Broderick returned to comics with the short-lived Future Comics. He was scheduled to work on the title Peacekeepers, but it was never published, and Future went out of business shortly thereafter. In 2004, Devil's Due Publishing revived Micronauts, with Broderick returning to the title. He drew three issues before it was cancelled.[14]

Broderick is known for his detailed, expressive art, and his characters' large eyes. There is some resemblance between Broderick's art and Michael Golden's late 1970s style. Broderick has acknowledged his admiration of Golden's work.[15]
